π : Spread the Love! Cloning Arrays Made Easy π
Want to create a quick copy of an array? Use the spread operator (...)! It's super simple:
const originalArray = [1, 2, 3];
const clonedArray = [...originalArray];
console.log(clonedArray); // Output: [1, 2, 3]
β¨ Pro Tip: This creates a shallow copy, so the clonedArray is a fresh array, but if your original array has nested objects, they will still be linked! Keep that in mind for deep copies. π

π Web Tip: Why You Should Add Version Numbers to Your CSS & JavaScript Files π§βπ»
When working on a website, adding version numbers to your CSS and JS files is crucial! Here's why:

When working on a website, adding version numbers to your CSS and JS files is crucial! Here's why:
1οΈβ£ Cache Busting:
Browsers cache your files to improve performance. But this can be problematic when you update your CSS/JS. By adding a version number (e.g., style.css?v=1.2), you ensure that users always get the latest version, not a cached one.
2οΈβ£ Easy Updates:
When you release a new update, changing the version number guarantees that users will fetch the newest files instead of relying on the old cached versions.
3οΈβ£ Debugging Made Easy:
Versioning helps identify which version of a file is causing issues, making debugging simpler.
π‘ Tip: Use a query string with each file update like style.css?v=1.3. You can automate versioning with build tools!

Benefits of Strict Mode:
βοΈ Catches silent errors by turning them into throw errors
βοΈ Prevents accidental global variables
βοΈ Disallows duplicate parameter names
βοΈ Makes eval() and arguments safer
βοΈ Restricts deprecated features
How to Use It?
Simply add this at the beginning of your script or function:
π Pro Tip:
